The high tension lines consist of three No. 4 hard drawncopper wires supported in the form of an equilateral triangle on Locke glass insulators, the two lower wires being mounted on4x5 in. two pin arms and the upper wire on a single pin arm at thetop of the pole. The lower insulators are on 12-in. locust pins withtwo-inch shanks and the upper insulator is on a i6-in. pin, and thewires transposed one-third of a revolution every mile.

Spring switches and frogs are usedthroughout the main line track and the switches are provided withdwarf target stands carrying standard steam railroad lights. Thetrack is laid on No. i oak ties 6x8 in. x 8 ft. spaces 24 in. betweencenters. Crushed rock ballast is used and is laid six inches deepunder the ties. This ballast is procured from the railwaycompanies quarries at Comanche, where they have erecteda stone crushing plant for this purpose. Some of the ings, jack-boxes are placed on brackets attached to the poles in sucha position that they can be readily reached from the car. Eachcar carries a telephone which can be attached to the jack-boxesat the regular telephone stations and telephone connections can bemade at any point along the line, by means of emergency poles car-ried on each car.
